Abruption placentae, also known as placental abruption, is a serious pregnancy complication where the placenta detaches from the uterus before childbirth. This condition can lead to heavy bleeding and may pose risks to both the mother and the baby. Symptoms often include abdominal pain, back pain, and vaginal bleeding. The exact cause of abruption placentae is not always clear, but it can be associated with factors such as high blood pressure, trauma, or smoking. Early diagnosis and medical intervention are crucial to manage the condition and ensure the safety of both the mother and the fetus.
